Cross-cohort generalizability of deep and conventional machine learning for MRI-based diagnosis and prediction of Alzheimer's disease.

Neuroimage Clin 2021 Jun 4;31:102712. Epub 2021 Jun 4.

Department of Radiology and Nuclear Medicine, Erasmus MC, Rotterdam, The Netherlands.

This work validates the generalizability of MRI-based classification of Alzheimer's disease (AD) patients and controls (CN) to an external data set and to the task of prediction of conversion to AD in individuals with mild cognitive impairment (MCI). We used a conventional support vector machine (SVM) and a deep convolutional neural network (CNN) approach based on structural MRI scans that underwent either minimal pre-processing or more extensive pre-processing into modulated gray matter (GM) maps. Classifiers were optimized and evaluated using cross-validation in the Alzheimer's Disease Neuroimaging Initiative (ADNI; 334 AD, 520 CN). Read More

Markerless Real-Time 3-Dimensional kV Tracking of Lung Tumors During Free Breathing Stereotactic Radiation Therapy.

Adv Radiat Oncol 2021 Jul-Aug;6(4):100705. Epub 2021 Apr 20.

Department of Radiation Oncology, Amsterdam UMC, Vrije Universiteit Amsterdam, Cancer Center Amsterdam, Amsterdam, the Netherlands.

Why is it important to report early possible COVID-19 PET/CT findings in cancer patients? Explaining with a case series.

Indian J Cancer 2021 Apr-Jun;58(2):248-258

Department of Obstetrics and Gynecology, Tepecik Training and Research Hospital, Izmir, Turkey.

Background: Coronavirus disease-2019 (COVID-19) causing a pandemic mostly results in mild symptoms; however, it can evolve into serious complications. It is emphasized that if the term from the recent anticancer treatment to the diagnosis of COVID-19 was short, the probability of serious events increased in cancer patients. Therefore, early detection of COVID-19 and prevention of serious events is very important. Read More

Central auditory maturation and behavioral outcomes after cochlear implantation in prelingual auditory neuropathy spectrum disorder related to OTOF variants (DFNB9): Lessons from pilot study.

PLoS One 2021 7;16(6):e0252717. Epub 2021 Jun 7.

Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Bundang Hospital, Seongnam, South Korea.

The cortical auditory evoked potential (CAEP)-based P1 component acts as a biomarker for cochlear implantation (CI) outcomes in children with auditory neuropathy spectrum disorder (ANSD). To date, early intervention primarily before the age of two years and six months of CI usage is necessary and sufficient to achieve age-appropriate cortical maturation and good prognosis. However, varying degrees of neural dyssynchrony, resulting from the etiological heterogeneity of ANSD, may preclude uniform application of this hypothesis to ensure auditory cortical maturation.

A reminder before extinction failed to prevent the return of conditioned threat responses irrespective of threat memory intensity in rats.

Behav Neurosci 2021 Jun 7. Epub 2021 Jun 7.

Donders Institute for Brain, Cognition and Behaviour, Radboud University Medical Centre.

After retrieval, reactivated memories may destabilize and require restabilization processes to persist, referred to as reconsolidation. The reminder-extinction procedure has been proposed as a behavioral reconsolidation-based intervention to persistently attenuate threat-conditioned memories. After the presentation of a single reminder trial, the conditioned threat memory may enter a labile state, and extinction training during this window can prevent the return of conditioned threat responses.
